- Be it known that I, ALBERT Wj. `HILL, of Branford, in the county ot' New Haven and State of Connecticut, have invented a new` Knob-Latches; andl do hereby declare that the following-isa full, clear, andfeXact de-1 scription of the saine, reference beingkhad to` the annexed-drawings, making a partof this speciication, in which--` 1 p `Itigniel isaface `view of the "face-plate of a lock Vprovided `with my invention.

This invention relates to a simple; ineans turned to suit either a` right orlettha-nd door, and consists` in` having the `outer part of the latch tted in a collar whichis `placed in the face platekifthelocl` case and allowed to rotate therein, tliecollar being retained or prevented from casually i turning` `by nieans of a catch orfastening` arranged `as hereinafter describedg j C 1i l To enablethose skilled in the art to fully` "Afrepresents the" casevof a lock B, the .face plate, andfC,wtlielatch, .the outer endofj which is `bnleledulatone sideas shown` at @if The inner part offthelatch` C, is offcylindrcal forniand liasla recessoigroovc 5,.

is of cylindrical forni `and is allowed to turn `freely in `the face-plate, and at the inner side i i` of the collar H, there are formed two ilat` i l or plane surfaces e, c; `said surfacesgbeing at `opposite `sides of the latch, as shown clearly in Fig.` 3, and to the inner side of the face plate above the latch @,tliere is a slidel, i

which `has a spring J, bearing on its `lower part g `)said spring having a tendency to keep.`

planesurface e, `of the `collar H. *The slide` y6o the lower` endof the slide" on the uppermost I,`pre`vents the collar` H, andconselquentlv i `tlielatch C, froin `casually` turning and` when thelock is fitted inthe door a screw (1.',which l passes through thenpper part of the facej` being casnally thrown up. f i

adinitof the `bevel d, of t-helatch bein'gsecured in oppositelpositionsas shown in Fig.

prevents the slide froin` rising or `41,5 and previous toifitting the lock in the proper position. .i The device it will be seen is extremely siinple and efficient and does not add to the ex` pense or' the construction ofthe lock.

` Having thus described niyinvention what l claim as new and desire to secure by Let- `1 placing of thelatchwG, of Vtlielock, in a collar H,\whi`ch"`is placedin the `face plate` B, and allowed toturn therein, thecollar `having two parallel .plane surfaces "e, e,` at itsinner pai't,`and nsed in connection `with the `slide I,"placed"a`t `theinner sideof the face-plate; all bengfarranged asand for `the purposeset forth.. u l i u i i.
